DEVICEFOR CQIE'II`.L!1\TG` THE COIN-EJECTORS IN CHANGE-GIVING-APPARATUS.

To all whom it may concern:

Be it known that I, SIEGMUND CHIGER, a' subject of the Emperor ofAustria-Hungary, residing at 65 Kurfrstendamm Berlin, Germany, haveinvented new and usetul Improvements in Devices for Coupling theCoin-lljectors` in Change-Giving Apparatus,

'of which the following is a specification.

The present invention relates to improvements in devices for couplingcoin-ejectors of change-giving apparatus to their .operating means, andis particularly applicable tothat type of change-giving apparatus 1nwhich the coin-ejectors are actuated by a push bar lor other pressuredevice to which they are coupled by the intermediary of couplingmemberswhich are moved lnto the couplingposition by the aid-of levers actuatedby the cams or projections ofcorresponding drums or disks.

the invention is to prevent those co-in-ejectors which `from any causewhatever do not contain coinsfrom being coupled to the drivingmeans/,and to retain these ejectors in their inoperative position inwhich position theejectors prevent, by means of certain auxlliarydevlces vconnected therewith, the levers operating the coupling membersfrom beiiag brought into action. o r According to the invention thelevers which operate the coupling members are mounted upon other leverswhich may properly be called supporting levers in such a manner as tomove, when actuated by the corresponding cam disks or drums, thesupporting levers into the path of oscillating frames or membersprovided with slots and adapted to assume two positions. ln theoneposition the lslotted frame or member Serves as an abutment againstwhich the supporting lever rests, whereby the corresponding actuatinglever is kept in a position, ready for operating the coupling memberunderthe iniuence ofthe corresponding disk or drum, while in the otherposition, the supporting lever enters into a slot of the oscillatingmember and thus renders the corresponding actuating lever inoperative.

In the accompanying drawings one construction of a device embodying thefea.- tures ofthe invention is shown by way of example.

showing the parts in various positions, Figs. 7, 8 and 9 illustratedetails.

The coin-ejecting slide 1 (Fig. 1) is provided with an opening o'rrecess 2 which serves for receiving a coin of a certain sort. In theconstruction shown it is assumed that the opening contains a 1 pfennigcoin. The coin-ejecting slide 1 is connected to a rod 3 by means ofwhich it is advanced for the purpose of ejecting a coin. The coinejector or the rod fixed thereto may be coupled by means of a couplingmember 5 to a transverse ejector bar 4 which is adapted to be moved inthe horizontal direction after the coin ejector 3 has been coupledthereto. The means for moving the push bar 4 do not form part of theinvention and may be of any known kind. This coupling member 5 may bebrought into the coupling position` by means of a projection G of arotatable disk or drum 7, which is loosely mounted upon a shaft 8 and isprovided with lateral pins or projections 9. By the side of the disk 7and fixed thereto is arranged upon the shaft 8 a gear 10 which mesheswith a toothed rack 11 which is operated in a manner similar to the rack141 described in my copending application Serial No. 749,171. By movingthe toothed rack l1 the disk 7 is moved from the zero position into anintermediate position in which the projection G is ready to act upon adevice by which the coupling member is moved into the coupling position.Fig. 3 shows the projection 6 in the zero position, this position beingindicated by full lines, and in the above mentioned intermediateposition which is indicated by dot-ted lines. 4

`The coupling member 5 is mounted upon the transverse push bar 4 and isadapted to slide relatively to the bar in the vertical direction, thebar engaging into suitable recesses 12 of the coupling member. Theconpling member 5 is actuated from above by a lever 14 pivoted at 13.This lever is actuated by a lever 15 which will hereinafter be calledthe actuating lever and which is pivotally mounted at 17 upon anotherlever -1'6 which will hereinafter be called the supporting lever. Thelever 16 is pivoted at 18. By turning the lever 16 the free end of theactuating lever 15 may be moved .into the path of the project-ion 6 orwithdrawn out of the reach ofthe projection 6. For this purpose thelever 16 is provided with an extension 19 with which coperates the arm2O of a lever 22 adapted to oscillate upon the fixed shaft 21 andprovided with an arm 23. To this arm is connected a rod 24 which ismounted upon a link K and is adapted to be actuated by means of a camdisk Z operated by a crank y. By turning the crank y the rod 24 iscaused to move the lever 22 into the position shown in Fig. 3 or toreturn same into the initial position shown in Figs. 4, and 6.

In'the positlon shown in Fig. 3, the lever 22 holds the lever 15 outsidethe path of the is moved in the direction of the arrow in' Fig. 4. Thepawl 25 is pivotally-mounted'/v upon a slide or rod 26 and is acted uponby a spring 27 in such a manner that when the rod is moved backward, bymeans ofv the handle n, that'is, in the direction opposit-e to thatindicated by the arrow, the

pawl may slide past the pin of the disk which at this time is locked. lThe pa'vvl 25 corresponds to the'paivl 5 of my copending applicationSerial No. 749,171 hereinbeore referred to, andv is only adapted to turnthe disk 7 by one tenth of a revolution, that is,

from the intermediate position into the operative position.

In order to prevent the lever l5 which is to be rendered operative bythe projection 6 from moving together with its supporting lever 16 aboutthe shaft 18, provision is madeto retain the supporting levers 16 in asuitable position. For this purpose the lever 16 is provided withl anose 28. When the lever 15 is pressed down the projection or nose 28presses against the-portion 29 'of an oscillating member 30 Which isprovided withv a slot or recess 31 and a cam arm 32.v

The arm 32 rests in the normal position of the oscillating member 30against a fixed stop 33 as shown in Figs. 4 and 6.

In order to return the coupling member 5 from the coupling positionshown in Fig.

6 into the' initial position shown in 'Figs 3 to 5, there is providedunderneath the'rod 3 and Within a stationary casingi 34 a-pusher 36which is slidably mounted and is actuated byv a spring 35. The pusher isprovided With a projection 37 and a lrecess or= opening-'38. In theposition of rest, the projection 37 of thepusher" takes into la recessornotch 39 of the rod 3. In order to hold the' pusher 36 and the:couplingfmember 5 Ain the operative positions (Fig. 6) even after theaction of the projection 6 has ceased, there' is provided a locking bolt40 which is slidably mounted'inthel bar 4 and takes into the 'recess 38of# the pusher. When the bar 4 is advanced in the direction of the arrowin Fig. 4, the lookingpfwlis- Withdrawn from the pusher 36, butthepusher cannot liftl the coupling member.

.When the bar 4 is moved in the oppos.ite direction, the coupling member5 slides with its lower inclined portion up uponthe pusher and raisesthe lever V14y andthe' The coupling member should' bev moved intol thecouplinglposition.shown in -Figir 6 onlyvvhen the opening 2 'of theejector' l contains a coin" as shown in Fig. 1. If the' opening. 2 isempty the slide or coinejector l should be moved into the inoperativeposition shown in Fig. 5. In order to move the ejector into thelinoperativeposition there is provided a reciprocating. rod I41 whichacts' upon the ejecton rod 3 by means of a conical member 42. Thisconicall member takes into a recess 43 ofthe rod '3; When the rod 41 ismoved wto the; right, the conicalv member 42 has the tendencyto move theejector 1- and the rod 3 into the position shown in Fig.v 5, in whichposition as 'above 'men'- tioned, the coupling member' 5 cannot bebrought into engagementwith the rod 3. This vcase occurs whenthetejector slide l. is empty. If the ejector slide contains the propercoin to #be ejected, it is prevented from moving: into the inoperativepositionrby a stationary pin 45 which projects upwardly;-

throu h a slot44 of the slide 1 (Figs. 1,;-2l

and' 9 and retains the slide vin its operative position through theintermediary ofi the,

coin.

In yorder to preventl the operating disk from damagingthe parts 14, l15,normally operated thereby when the ejector l has been brought into theinoperative position (Figo.

5) inwhich the coupling. member 5 cannot enter the rod' 3,the'follotvingdevice is provided: The rod 3is provided with an arm 46Vwhich carries a two-armed lever 48, 49,'V which under the influence vofa- Weight 47 has the tendency to assume theA position shown in Fig. 4.If desired a springmight be provided instead oftheweight 47. The I* flever 16 is provided at its tail end with an extension 50 having aninclined cam surface 51.` When the rod 3 is moved in thedirec-v tion`opposite to that indicated by the'arrow, into the'inoperative positionshown in Fig. 5, the arm 48 is brought -into close roximity to theinclinedl cam surface-51.` en after- Ward the diskis moved, fromA the;intermediate position intothe position shown in Fig. 5, the leverf16`is.' oscillated inthe up- Ward 'direct-ion. Duringfthis upwardjmovef lment the lever 16p-moves the'arm- 49 to the: right, shown 1n Fig. 5, andthe letter moves incastri the lever 30 into such a position that the jpart 29 of the lever is moved out of the path change-giving of theprojection 28, the latter projection entering the slot or recess 3l.'lhe rod 3 is returned to the position shown in Fig. Il by theprojection 52 of the rod Lil. The move ment of the rod 3 by the rod il`is limited by the projection 87 of the pusher which takes into a recess39 o-f the rod 3.

The lever 30 is provided 'with a lat-eral pin. 53 which engages into aslot 5d ofa link pivoted to the lever 22 at 55. This arrangement servesfor moving the part 30 into the inoperative posit-ion lshown in F ig. 3,by the movement of tl elxever 22. ln the .set position the lever l5 ismoved out of the reach of the projection 6, and thedisk is, therefore,movedl into the intermediate position. shown in Fig. Ll' Withoiitactuating the lever 15'.
